al_ustr_offset(3)                                            al_ustr_offset(3)

NAME
       al_ustr_offset - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              int al_ustr_offset(const ALLEGRO_USTR *us, int index)

DESCRIPTION
       Return the offset (in bytes from the start of the string) of the code
       point at the specified index in the string.  A zero index parameter
       will return the first character of the string.  If index is negative,
       it counts backward from the end of the string, so an index of -1 will
       return an offset to the last code point.

       If the index is past the end of the string, returns the offset of the
       end of the string.
